Abstract

The utility model provides a composite pipeline optical cable which comprises at least an optical cable, a micro tube and a fixing part used for fixing the optical cable with the micro tube. The composite pipeline optical cable is mainly laid in pipelines or along the same gutter with petroleum pipelines or highways, and can reduce the laying cost of optical cable, improve project progress and facilitate the later expansion of pipeline.

Description

The compound pipeline complex pipeline optical cable

Technical field:

The utility model belongs to the fiber optic cable communications field, and is main with to be used for pipeline interior or relevant with the compound pipeline complex pipeline optical cable that ditch or highway lay along oil pipeline.

Background technology:

Along with the step of FTTH closes on day by day, each communication operation commercial city for the consideration of cost, utilizes existing conduit resource laying optical cable in pipeline more and more to be subjected to the favor of each big operator carrying out the network capacity extension.Utilizing gases at high pressure that optical cable is blown in the pre-buried pipeline is a kind of mode comparatively commonly used now.Common air-blowing duct optical cable is representative with ordinary optical cable GYTA, GYXTA and micro optical cable GCYFTY, GCYFXTY generally, and wherein the system of laying of ordinary optical cable is elder generation's pre-buried silicon core pipe on the optical cable route, then optical cable is sent in the pipeline with the mode of air-blowing.For micro optical cable because optical cable cable footpath is less, the stretch-proof of optical cable and lateral pressure resistant and moistureproof ability a little less than, in order to increase protection, also in silicon core pipe, lay one or more microtubule more in advance, and then little cable is sent in the microtubule little cable.But these two kinds of system of layings all are divided into two to three steps, and its shortcoming is that engineering cost is higher, and construction speed is slow.

Summary of the invention:

The purpose of this utility model is in order to overcome above shortcoming, a kind of laid down cost that reduces optical cable to be provided, improve project speed, being convenient to the compound pipeline complex pipeline optical cable of the later stage dilatation of same pipeline.

The purpose of this utility model is achieved like this:

The utility model compound pipeline complex pipeline optical cable comprises at least one optical cable, microtubule, and with the fixture that optical cable and microtubule are fixed together, the quantity of optical cable and microtubule depends on the needs.

The sheath of above-mentioned fixture for optical cable and microtubule are fixed together forms cladded type pipe cable.

Above-mentioned fixture is with optical cable and the fixing binding rope of microtubule binding, form binding type pipe cable, it has all characteristics of cladded type pipe cable, and in addition, binding type pipe cable can be transported to the infield respectively with optical cable and microtubule, tie cable when mounted, so the laid length of binding type pipe cable is longer, when mounted, optical cable and microtubule are emitted from the cable dish simultaneously, tied group together, together puts into pipe.

The center optical cable that is positioned at the center is arranged in the above-mentioned compound pipeline complex pipeline optical cable.

The utility model is that ordinary optical cable and microtubule are combined.After utilizing existing conduit resource or ditching pipe cable direct-burried, (being equivalent to imbed optical cable and microtubule underground simultaneously) is later on again according to market demand dilatation by stages, little cable is blown in other microtubule in batches, so both reduce construction procedure, also saved initial investment, and avoided a large amount of optical fiber idle.

Be below the utility model pipe cable aspect executive cost and project progress with the comparison of known other two kinds (ordinary optical cable, micro optical cables).

1, the comparison of engineering cost

We were the engineering cost that example is come these three kinds of system of layings of comparison because of needing dilatation to increase a same optical cable again to have laid one 24 core optical cable on a route afterwards.The interior price of time of supposing twice engineering does not change.

Table 1: the expense contrast of three kinds of construction methods

Find out from above whole engineering total expenses minimum be the pipe cable, compare with micro optical cable and to have saved 160,000 yuan! As continue to increase the consumption of optical cable, it will be more obvious managing the low advantage of cable construction cost so.

2, the comparison of project progress

Contrast from project progress, because the quantities unanimity of ditching backfill is not made comparisons here.Because the employed optical cable of pipe cable dilatation is a micro optical cable, its air-blowing length is than common length, the maximum air-blowing distance of general ordinary optical cable has only 1.8km, and the maximum air-blowing distance of little cable can reach 3km, if adopt the mode of blowing from the middle to both ends, put little cable an air-blowing and will blow 2.4km more than general cable, the people who did the air-blowing construction knows: the time of air-blowing mainly all consumes on the preliminary work of haulage equipment between the air-blowing point and air-blowing, and the time of air transporting optical cable is not long in pipeline.Air-blowing length is long, is equivalent to reduce on the route of equal length air-blowing construction point, has saved the engineering time.The construction speed that is three kinds of forms of construction work below compares.

Table 2: the progress contrast of three kinds of construction methods

Manage the construction speed of cable as can be seen from Table 2 and saved about 15 days than preceding two kinds of forms of construction work, the lease expenses of artificial, working fuel cost, equipment etc. is all greatly separated minimizing.The overall weight of this outer tube cable only than the heavy 10kg of silicon core pipe commonly used, considers that from the angle of weight the difficulty of construction of putting pipe is suitable.

The utility model compound pipeline complex pipeline optical cable has reduced construction procedure, has saved construction cost than other two kinds of forms of construction work, and has improved project speed.It can increase by 1 to 7 and preset communication path in existing or new pipeline communication system.Be convenient to later stage dilatation with a pipeline.When the new pipeline communication circuit of needs increase maybe needs to lay the optical fiber of different model, just need not spend extra-pay again.
